GUIDE-BOARD FOR SELF-BINDING HARVESTERS.

SPECIFCATIONformng part of Letters Patent No. 648,818, dated May 1, 1900.

Application tiled January 30, 1899. Serial No, 708,936. (No model.)

To all whom it may concern:

Be it known that I, WILLIAM WEBBER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Il1inois, have invented'a new and useful Guide- Board `for Self-Binding I-Iarvesters, of which the following is a specieation.

My invention relates to improvements in guide or wind boards for guiding the heads of the stream of grain that is iiowing into the binding attachment of a self-binding harvester; and the objects of my improvement are, first, to provide a board that will auto-- matically act yas a guide for the heads of the grain when the binding attachment is adjusted on the frame of the harvester for binding short grain centrally, which board will when the attachment is adjustedrrearwardly forbinding long grain centralljT fold against the binder-deck, so that thelong grain can passl over it without being retarded, and, second, to the means for actuating'this board bythe movement of the bindingattachment. Iatt-ain these objects with the mechanism illustrated in the accompanying drawings, in which` Figure 1 is arear elevation of so much of the frame and binding attachment of a selfbinding harvester as is necessary to show my improvement. Fig. 2 is a top view ot my improvement with' the parts of -the machine to which it isattached. Fig. 3 is an enlarged top view of the bar' upon which the board is mounted; and Fig. 4 is an end View of the deck -guide and deck, showing the bar to which the board is attached.

Similar letters refer to similar parts throughout the several views.

-The-grain after being cut by a modern selfbinding harvester is transported on endless. carriers over the main or driving wheel of the. machine to abinding attachment, where it is apportioned into bundles and bound and dis'- charged. There are many danses that influence the position of the grain on the carriers, tending to move it to the front of the machine lVhen the machine is of the closedaelevator type, the side-boards will act as guides for the stream-of grain; but when the machine is of the modern open-elevator' construction, the rear guideboard being disp pensed with, the stream in going up a hill will be carried so far to the rear as t-o manyA times be bound too close to the butts. A positive guide or wind board is therefore necessary to carry the stream of grain into the binder. I-Ieretofore such boards have usually been held by springs, so as to be forced' out of the way when long'grain was encountered.; but in my improved construction the board when acting asa 'guide is rigidly held, thus makinga positive chute to the binding device.

In the drawings, A. represents the main wheel of the harvester, and itis shown in dotted lines; B, the elevator-frame, and C the main harvester-frame- Attached to this framing on the support D is a binding attachment F. The grain is carried over the elevator B and deposited upon the deck G, down which it slides to the binding devices. is adjusted back and forth along the delivery end of the elevator, the deck G sliding in the fixed grooved rail H by the adjusting-lever I.

VWhen the b inder is adjusted forward, as shown in Fig-L 2,

the heads of the grain are supported and the mechanisms upon thel machine are covered by a supplemental apron J, which is secured at its upper edge to the ixed The binder rail H by screws 4 or otherwise and projects outwardly over the front edge of the deck.

The guide or wind board H is positioned transversely of the deck of the binder and is supported and held in place by the pivoted bar I. This bar is pivoted to the harvesterframe-at its inner end and extends outwardly clo e to and Aabove the surface of the deck G.

In the drawings it is shown pivoted at is tothe fixed grooved rail H. The inner end of the bar I' is flattened, as shown in Fig. 3, and this attened portion is given a quarter turn or twist 2, also clearly shown in Fig. 3. The board H is heldupon this bar by a staple i, secured to the board near its inner end, and a corresponding staple i', secured near the outer end of the board. Thev bar I' passes loosely through these staples and forms a pintle, upon which the board may be turned into vertical or horizontal --position as on a hinge.`

To govern the movement of the board,a bracket J'Iis secured to the deck G of the binder, andthe pivoted bar I passes through this bracket, which is boredlarge in order that the bar, whose'upper end is ixed, may slide therethrough as the binder-deck is adjusted for long or short' grain. The staple i near the outer end of the board .H' is provided With two ears, and the bracket J' is held upon the bar between these ears. The boardis thus vkept in iixed relation to the'bracket and compelled to slide along thebar with the bracket as the bindernioves.

The movement of the binder is in a straight linegand the board H being held thereto by the bracket J" moves bodily with it. The r'od4 l', however, being pivoted at' a liXed point at its inner end, 'its outerend describes an are,

'and the board H must move relatively to the i bar and lengthwise'thereof as the binder is adjusted. As shown in Fig. 4, the staple t" f in g a-long the bar, gives the board the quarter- 'near the upper end of the board fits the dat part of the bar J, and las the board is slid on the bar its movement will conform to the turn or twist in the Iiat part of the bar. It will therefore be turned down practically parallel to the surface of the deck whenthe board `is slid upwardly along the bar and will be turned urp, so as to stand at right angles to the deck,

.when it is slid down on the-bar.

In operation the binder is adjusted by means of the lever I in the usualmanner to place the baud centrally around the grain. This fore-and-aft movement-ot' the binder (including the deck G) carries with it the bracket 'J' and the board Il', thus sliding the boardv along the pivoted bar I'. The staple i, movturn corresponding to the twist 2in the bar and throws the board do'wn on the deck when` the binderis moved forward'into the position shownin dotted line's in Fig. 2. 'When the I i binder is thrown back, the bracket J slides the board H outwardly along the bar I', aild as the4 board moves along the' bar the twist or turn in the dat 4part of the.bar causes the and means foigturnin'g the board on the baras the binder is adjusted.

2. The coinbinationpf an adjustable binder, a bar connected to the harvester and moving with the binder, aboard mounted on the bar,

and means for tu rning` the board as the binder is adjusted.

3. The combination, to form a guide or windboard for self-binding harvesters, of a binding attachment adjustable along the delivery end of the harvester, a board having its receiving end positioned at the-delivery end of the elevator, and its discharge end moving with the binder, and means whereby the board lis turned down upon the binder-deck when the binder is adjusted for long grain and may be turned u p perpendicular to the deck when adjusted for short grain.

4. The combination, with a binder adjustable on the harvester, of a bar pivoted at one end to the' harvester, abracket fixed to thel deck'ofthe binder which serves as a guide for the other end of the bar, a board mounted on the bar the delivery end of which is controlled by the bracket, aA guide on the board and a` twist in the bar, substan tially for the purpose specified.
